IVIA'ITRESS-MAKING MACHINE.

Application filed August 2, 1907.

Speciieation of Letters Patent.

Patented April 6, 1909.

Serial No. 386,740.

To all whom it may concern.'

Be it known that l, CHARLES W. WHITE, a citizen of the United States, residing at W'aco, in the county of McLennan and State of Texas, have invented certain new and useful Improvements in Mattress-Waking Machines, of which the following is a speciiication.

The present invention relates to mattress making machines of the general type wherein the material to be assembled and condensed to the proper shape is fed into a suitable frame, which is then bodily moved into the tick and withdrawn therefrom, leaving the mattress forming material in the tick.

The present invention is designed more particularly as an improvement on Patent No. 813,470, issued to me February 27, 1906, and to said patent attention is directed for a general understanding of this type of niachine.

The invention herein described is an improvement on the prior patented structure in several particulars, whereby a more simple and equally efficient machine is produced and it consists of the parts and combinations to be hereinafter described and claimed.

Referring to the drawings wherein similar characters of reference are used to indicate corresjiionding parts in each of the several views :A-Figure 1 represents in side elevation a machine embodying the features of the present invention, Fig. 2 is an end view thereof, "i" 1. i?. a lai viVx I of the machinel F'U'. 4 11g islpii en 1g is a longitudinal sectional view; Fig. 5 is a cross-section on line .5e-5, Fig. 1; Fig. 6 is a detail view, showing the adjustable door supporting beam and adjustable door and means for adjusting the same and Fig. 7 is a detail sectional view on line '7*7 of Fig. 3.

Referring to Fig. 1 of the drawings, the main supporting frame for the operating parts of the machine comprises suitable uprights A, which, near their lower ends, are joined by sides A suitably secured thereto and preferably braced in any desired manner to constitute a convenient and suitable framework. The uprights A are extended above the side pieces A to constitute a receiving chamber, having, as shown in Fig. 1, the pivotally mounted swinging panels A2 provided with hinged extensions A3 and Al; extensions Af constituting doors through which access may be had to the interior of the chamber for purposes of inspection.

Supported on the main framework in any suitable manner and extending transversely between the sides A are the sprocket wheels or pulleys B and B2, Figs. 1 and 4, and about these sprockets or pulleys a slatted apron Bi passes, said apron constituting the bottom of the main frame between the sides A, as more clearly shown in Fig. 3. One of the sprocket wheels or pulleys B2 is adjusted toward and from the other by suitable means, as B3, which may be similar to that disclosed in my former patent referred to.

At one end of the machine, as in Figs. 1 and 3, is the tick support B5, B, formed substantially as in my former patent so as to support the tick. Both the upper and lower sections, B5 and B, of the tick support, are, as shown in Fig. 3, adjustable in width, as in my said patent, to provide for mattresses of different widths. j

ln my former patent the slatted apron was given both a forward and a reverse feed, whereby it performed the double function of inserting the mattress frame and mattress into the tick and then withdrawing the forming frame therefrom. This is also true of the machine herein described and, therefore, need not be further set forth, as a suflicient generall disclosure may be had by referring to my said former patent, No. 813,470.

ln my present machine the compression frame C and the means for raising and lowering the same are, generally speaking, similar to the respective parts in my former patent, No. 813,470, to which reference is hereby given for a clear and thorough description of the same. ln the present form of my invention this mattress forming frame consists of a series of slats il, which are adjustably connected together and operated by lazy tongs H. To the exterior series of slats are rigidly connected uprights H2. A plunger D similar to that described in the patent referred to and similarly adjustable with the slats H of the mattress forming frame is connected to said frame either fixedly or in such manner as to be longitudinally adjustable on the same, as will be readily understood on reference to the above patent.

One feature of this invention is a device for holding the mattress material in position during compression. l-leretofore in machines of this general class, when the compression frame, similar to frame C, was lowered into operative position, the mattress material of a light feathery nature was forced outward from the lower end of the frame and gathered in a thick mass near the opposite end thereof, thus producing a 'filling of varying uneven density which afterward had to be given additional treatment to put it in proper shape. To overcome this serious objection, I have provided a plurality of long, wide slats E, ivotally connected in the preferred form to locks e attached to plunger D, said blocks being sufficiently high to have the hinged connection above the plunger D and to allow said slats to swing down onto the mattress material previous to the lowering of the compression frame C. The slats, actn ing separately, as they do, tend to hold the material in position to be uniformly conipressed by the frame C. Owing to the fact that the slats are spaced apart, as clearly shown in Fig. 3, as well as to the fact that they act separately on the mattress material, said material is not hunched or gathered., as is the case where the solid compression frame is used alone.

In order to hold slats E in their oaerative position, I have provided a bar or plank E, hingedly connected to the end of the mattress forming chamber and adapted to drop and overhang the slats when they are raised. In order to completely and tightly inclose the mattress forming frame in all its adjusted positions so as to prevent any of the mat tress material falling between the sections A4 and the uprights H2, it is necessary to adjust the adjacent panels A2 of the chamber wherein the mattress material is compressed.

The panels A2 are pivotally mounted at a on the uprights A so as to swing bodily inward.

.Sections A4, hinged at a to panels A2, are extended beyond the framework of the machine to completely inclose the entire run of the apron. These sections so extended are provided with internally screw-threaded nuts g adapted to receive the opposite reversely threaded ends of a rod G lying above the upper run of the apron and being supported in beams gf in the framework of the machine. A like rod is similarly mounted at the opposite end of the machine beneath the lower run of the belt, and the two geared together for simultaneous operation through sprocket wheels G', mounted respectively on them and a cooperating sprocket chain G. In the preferred form of the device, the nut (,1 is made in two parts and formed with a flange or toe g2 on each part adapted to embrace between one of said flanges and the opposed face of section A4 the upright H2 to thereby draw said upright in one or the other direction, as said nut g travels on the aforesaid screw G. Cbviously, these may be separate and individual nuts for moving the slats and the sections A4, if desired.

In order to adapt the compression frame C to the various widths of the mattresses to be formed, I have constructed it of several sections adjustably connected, comprising a central relatively stationary member c and two relatively adjustable side sections, c and c2, said side sections being adapted to slide upon said central section, as clearly shown in Figs. 2 and 6. Sections c and c2 are respectively hinged to adjustable sections f and f of compression frame support F. The sections of the tick support members B5 and I5@ are also, connected to the sections of the compression frame support F in such manner as to be adjustable therewith, as will be readily understood from Figs. 2 and 6, of the drawings. For adjusting said sections f and ff and their connected coinpression frame sections, I have provided a rod G2 similar in construction and operation to rods G, said rod being mounted in journals in the compression frame lifting racks, I. Rod G2 is provided with a sprocket wheel G12, and is operated simultaneously with rods G through sprocket chain G13, as is apparent on reference to Fig. 2 of the drawing.

The operation of the machine is as follows: Material is fed onto the compression chamber, slats E are lowered tovhold the material in place, compression frame C is lowered onto the slats E to compress the material, lever X is operated to throw the friction drive wheel il into driving contact with the direct drive friction gear X2, whereby the entire mattress forming frame through its connection with the slatted apron is fed into the tick through the tick support. At the end of the feed the lever is operated to throw driver X into contact with reversing friction X3, whereby through the sprocket chain connections a reverse movement of the apron and connected mattress forming frame is given and the frame is thereby withdrawn, If a mattress of different width is desired, the rods G and G2 are operated as previously set forth, thereby adjusting side pieces A4,

the slats E, the slats II, the plunger D, the

door sections C and C2, and the adjustable sections of the tick support, all in proper proportion. If am attress of different length be required, the plunger D is adjusted longitudinally, as will be readily understood in reference to my former patent.

It is obvious that many changes may be Ymade in the details of construction and lIO during compression, a slatted apron, and an adjustable mattress forming lran'ie supported on said apron, and means i'or moving said slatted apron, :first in one, and then in the opposite direction.
